Chlorine-based gamma-biological nitrogenous fertilizer and preparation method for same

Abstract

The invention discloses a chlorine-based gamma-biological nitrogenous fertilizer and a preparation method for the same. The chlorine-based gamma-biological nitrogenous fertilizer comprises gamma-poly-glutamic acid, wheat straw extract, a microbial agent and a secondary nitrogen element, wherein the gamma-poly-glutamic acid and the microbial agent are integrally prepared by a fermentation process; the wheat straw extract is obtained by extracting and processing wheat straw tender shoots; the secondary nitrogen element is obtained from related compound powder; the chlorine-based gamma-biological nitrogenous fertilizer comprises 0.1 to 5.0 parts of the gamma-poly-glutamic acid, 2 to 20 parts of the wheat straw extract, 3 to 10 parts of the microbial agent with bacterium content of more than 2 billion per gram, 60 to 80 parts of urea with N content of 46 percent and 10 to 25 parts of ammonium chloride. According to the chlorine-based gamma-biological nitrogenous fertilizer and the preparation method for the same, the utilization rate of nitrogenous nutrition can be increased; under the synergistic effect of the gamma-poly-glutamic acid and the wheat straw extract, a soil micro-environment is improved, the absorption of nutrients is promoted, the yield of crops is improved, and the disease resistance, the stress tolerance, the interference resistance and the successive cropping tolerance of plants are improved.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial fertilizer production, in particular to a chlorine-based γ-biological nitrogen fertilizer and a preparation method thereof. Background technique [0002] In modern agricultural production, chemical fertilizers are playing an increasingly important role, among which the consumption of nitrogen fertilizer is the largest, about 30 million tons (pure conversion) per year. However, the average loss of nitrogen fertilizer is as high as 45% through volatilization, leaching and runoff, resulting in an annual loss of more than 13 million tons of nitrogen, which is equivalent to tens of millions of tons of urea. What is more serious is that chemical fertilizers have and will continue to It has brought many adverse consequences to our living environment, such as soil compaction, water pollution, agricultural product pollution, greenhouse effect and other issues. [0003] Commonly used biological...

Problems solved by technology

[0010] The production of γ-polyglutamic acid can be produced on a large scale by biological fermentation technology, which can not only improve the nitrogen utilization rate of fertilizers, but also have a certain water retention effect on plants, and can reduce the water consumption required for plant growth. However, as a functional additive for a suitable fertilizer, its role and efficiency are far from being fully realized; how to screen substances that can produce a synergistic effect with γ-polyglutamic acid and jointly develop a biological fertilizer to increase γ-polyglutamic acid The effective role of amino acid provides more effective and economical microbial fertilizer for the country and farmers, thus creating greater social and economic benefits
